Where to find new or used parts

Are there any used parts suppliers for GEM carts? My immediate need is difficult to explain. I have a 2010 Gem xL XD with hard doors. I need a replacement window, but also the grooved trim the window slides in. I can find the window, but the assembly doesn’t come with the trim. I can get an entire door, but that’s expensive. Are they parts graveyards where I can get them off an older one?

Keep searching, there’s a place in Florida. Have you found them?

I’ve talked to two places in Florida and one in Arizona. All I can find are whole (expensive) doors.
